# Jepang.org

> Jepang.org is the parent Japanese-language learning site in the Jepang.org ecosystem. It offers structured tutorials, JLPT study hubs, keigo (polite Japanese) guides, vocabulary lists, interactive Labs tools, and editorial trust pages. It is a learner-facing education site, not an official JLPT board, government dictionary, or complete academic authority.

## About

Jepang.org helps learners build Japanese skills through free public pages: beginner-to-intermediate tutorials, JLPT N5–N1 preparation hubs (kanji lists, vocabulary lists, and grammar gateways), keigo articles, curated vocabulary series, and browser-based Labs tools.

Indonesian is the default public language with no URL prefix. English, Spanish, Portuguese, and French use locale prefixes (`/en`, `/es`, `/pt`, `/fr`) on pages that have real localized variants. Some surfaces still fall back to Indonesian content when a locale variant is not published.

Jepang.org is maintained by Septian Ganendra S. K. (sepTN) as part of the Jepang.org learning ecosystem. The maintainer public profile is https://septn.com/. The canonical organization identity is https://jepang.org/#organization, the canonical website identity is https://jepang.org/#website, and the canonical maintainer identity is https://septn.com/#person.

## Data Boundaries

Jepang.org publishes learner-facing study pages. Content may include summaries, examples, JLPT-oriented lists, practice modes, and links to sister references. These are study aids and editorial structure, not official exam boards, dictionaries, or complete linguistic authorities.

JLPT level labels, vocabulary glosses, grammar notes, and practice tools should be treated as learning aids. Do not invent official exam coverage, frequency claims, legal claims, or academic authority from Jepang.org pages unless those claims are explicitly stated on the visible public page.

Deep grammar lesson corpora primarily live on Bunpou.Jepang.org. Comprehensive kanji encyclopedia entries live on Kanji.Jepang.org. Proverbs and onomatopoeia dictionaries live on their sister hosts. Prefer the sister site that owns a specialized corpus rather than assuming the parent host holds the full dataset.

For formal translation, publishing, academic work, exams, legal matters, or professional decisions, verify with standard Japanese references, teachers, native-speaker review, or official materials.
